# Check box input A boolean input interaction item is used when the operator needs to answer a true/false question of lesser importance. Boolean inputs show up as check boxes in the Flow Client. Boolean inputs have the following properties: * **Target Variable**\ The name of the new variable in which to store the choice entered. A positive choice (checked) creates a variable value of true, while a negative choice (unchecked) creates a variable value of false. * **Prompt**\ The label to display over the check box input field. * **Default Value**\ Either false (unchecked), true (checked) or a variable reference to a value of either false or true. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
